Soaring costs to beat the heat and humidity in Singapore and other Southeast Asian countries are no joke. They take a deep cut into your profits.
If there were a cheaper way to stay cool in these places, would you be interested?
The good news is that the solution to high electric bills is right above you in the sky. The sun’s energy is the driving force behind a cost-effective and energy-efficient solar air conditioner.
Below you’ll find the top 5 reasons why a solar-powered air conditioner is your answer to hot weather woes in your building or facility.
1. A solar air conditioner saves you money.
Savings on electricity up to 40% every month are typical with a solar aircon unit. It may sound too good to be true, but it’s not!
Utility expenses are much lower when you use solar air conditioning units, because they don’t depend on the national power grid to supply electricity. Instead of relying on the grid, the photovoltaic cells attached directly to the solar air conditioner capture radiant light energy and transform it into electrical energy.
There are solar aircon systems that can use this direct current (DC) to operate. These are called “off-grid” because they never pull alternating current (AC) from the power grid.
The off-grid solar air conditioning units require a battery backup for night use and cloudy days.
On the other hand, a solar hybrid air conditioner works differently.
On sunny days, the solar hybrid aircon unit uses only free sun power. It is this energy that powers your air conditioning unit. So, your monthly electric bill from the utility company will be lower because of this offset.
At night and on cloudy days, the solar hybrid air conditioner operates using the alternating current of the power grid. This is when it will cost you money.
Although there is some expense for electricity with a solar aircon, it is significantly smaller than a conventional air conditioner that runs entirely off of the power grid.
How much electrical power do you need to keep all of your building cool? Maybe you have an auditorium or lecture hall to cool as well as smaller conference rooms. If you wish to cool larger spaces or several floors, more solar modules can be added to your system in order to accomodate your needs.
2. A Solar-Powered Air Conditioner Is More Energy Efficient.
Would a SEER rating for your AC system of up to 35 interest you?
You can get that with a solar aircon.
SEER stands for Seasonal Energy Efficiency Ratio. It’s an industry term that gives you an idea of how energy efficient a HVAC system or an appliance is.
The SEER is equal to cooling output (measured in British thermal units, BTUs), divided by electrical energy input (measured in watt-hours, wh). The higher the SEER, the less energy your cooling system uses.
If your campus runs on conventional AC, its SEER rating is probably in the teens or low 20s. You can find out by looking at the white or yellow label prominently displayed on the machine, or consulting your owner’s manual.
The minimum required by law in Southeast Asian countries may vary from place to place, but usually is about 13.
Over time, air conditioning units may lose efficiency if they’re not properly and regularly maintained. Preventative maintenance, like changing the filter and getting regular tune ups, is essential to keeping energy efficiency at your system’s max.
If you’re a building or facilities manager, you know that replacing a system that wastes energy — as indicated by a low SEER — is a wise investment. It will keep utility costs in check.

3. A Solar Aircon Has a Fast Return on Investment (ROI).
Would a ROI of less than 2 years catch your eye? This is what you’d enjoy if you invest in a solar-powered air conditioning system.
What this means in terms of dollars is at the 2-year mark (or thereabouts) the solar air conditioning system will do more than just pay for itself, making you break even and then some.
You’ll begin saving (or earning) money! Then you can turn around and use the extra cash to develop your facility in other ways.
If you’re like most people, you need to “do the math” before you’d believe it. Yes, seeing is believing.
To prove it to yourself that an investment in a solar AC is worthwhile, a special calculator will come in handy.
To use the calculator, you need to input a few details unique to your situation. Your country, for one.
Then you’ll need to plug in values for:
- The number of days per year that the solar aircon will operate
- The time of day when the system will be in use
- The total BTU used per hour by the AC unit in your facility.
Try it for yourself and see how fast the ROI from a solar aircon system will materialize in your bank account.
4. Solar Air Conditioning Is Locally Renewable.
As a Southeast Asian, how important is energy independence to you?
I’d bet it’s extremely important.
Think about this for a moment:
If all businesses, government offices, and schools in Singapore, Malaysia, Thailand and neighboring countries used the sun for their energy needs, including powering their air conditioners, energy independence would be closer than ever before.
Currently, the region is the fastest growing in the world for energy demand, accelerating it toward being a net importer of fossil fuels.
Unfortunately, the rapid rise in fossil fuel use has produced higher levels of air pollution and increased carbon emissions. These represent threats to public health.
Also, burning fossil fuels is the primary reason for climate change. Its effects, in the forms of extreme weather events and sea level rise, are becoming more and more pronounced all around us.
To lessen the future negative consequences of climate change, businesses can capitalize on the renewable energy that’s readily available throughout the region: the sun.
Investing in a solar-powered air conditioning system is a great way for businesses to participate in the solar revolution.
5. Solar Air Conditioning Reduces Your Carbon Footprint.
As climate change intensifies all over the region, every way that businesses can take to reduce their carbon footprint is important.
For starters, why not invest in a solar-powered aircon?
A recent survey of Singaporeans demonstrates the overwhelming public support for efforts to reduce carbon emissions.
Young people especially are extremely concerned about climate change, and fearful about what the future has in store for them.
Converting to a solar air conditioner is proof of your company’s concern and demonstrates your commitment to building a greener world.
For example, in 2015, the NEA pledged to reduce carbon emissions 36% by 2030 to 2005 levels.
This ambitious goal cannot be achieved without everyone’s support.
Also, the BCA instituted a Green Mark program to differentiate companies making their properties sustainable from those which are not.
As a building or facilities manager, you can get on board and contribute to the success of these bold climate-related initiatives by investing in a solar air conditioner.
